Customer Ratings & Reviews

They're batteries. They seem to work well, but are getting expensive like most name brand batteries.

Don't know yet. Just put one in so we will see. I've used this brand before and they were good

Very useful and long lasting. Had to purchase for a wall stud

Good, easy to instill and last long for the cost of product.

Worked as expected, long lasting and powerful. Will buy again

These are energizer batteries, and they do the job and last a long time. Great batteries for my smoke alarms in my home.

Proven quality. Needed to replace smoke detector batteries.

Long lasting batteries! “Nothing outlasts the Energizer!”

The Energizer MAX 9V Batteries (2 Pack), 9 Volt Alkaline Batteries are wonderful. Great name recognition that I can trust.

Battery works fine. Does what it's supposed to do.

Good for my electronic devices and I have used them for years, and will continue to do so.

So far it is giving the services it is required. I am still using the battery

The product has a high quality and I like it so much

I can always depend on them being fresh when I buy them. If I store them for long periods of time they still hold a charge.

Always a reliable product. Purchased for grandsons remote control car. Long lasting even with heavy usage.

The Energizer batteries are good performing. They met my expectations.

We always use Energizer batteries and they always last a while. These batteries have worked great with our daughters walkie talkies.

I purchased Energizer Max batteries 9v 2 pack to replace the old batteries in my smoke alarm

Not much to write here other than they both work and for now have not gone dead in my smoke detectors.

These 9V batteries are always great to have on hand during the holidays when gift-giving for toddlers or electronics.
